Read cached output line-by-line This avoids loading potentially gigabytes of output into memory, which can cause OOMs. Fixes #7736. This does not add a test as I don't really want to generate gigabytes of output (that seems like a bad idea) -- and it's unclear how to test other than by causing OOM on (most) CI systems, and it's unlikely that we'll actually regress here.

Fix cache replay including extra newlines. The compiler output cache replay was changed in #7737 to use `BufReader::read_line` instead of `str::lines`. `read_line`, unlike `lines`, includes the trailing line ending. The code is written assuming that the line endings are stripped, so make sure they are stripped here, too. This only happens for non-JSON messages, like `RUSTC_LOG`.
